Question
Consider the case where the computerization described in paragraph five has been implemented. So, the average service time for the counters engaged in accountable transactions
Consider the case where the computerization described in paragraph five has been implemented. So, the average service time for the counters engaged in accountable transactions has been reduced from 2.5 minutes to 1.5 minutes. Also, the need for customers to buy stamps for accountable transactions has also been eliminated.
a) Assume that there is a common queue for accountable transactions. In other words, assume a separate queue for each of the following: 1) Counter for savings bank services (SB); 2) Both counters for accountable services (A1&A2 combined, so that there is only 1 queue for accountable services); and 3) Counter for stamps and stationary services (SS).
1. Calculate a customer's expected waiting time in each of the three queues
2. Calculate the average number of customers in each of the three queues
3. Calculate a customer's total expected time in the system for each queue
4. Calculate the average time a customer spends in the post office, averaged across all customers.
b) Now assume that there is only one counter for accountable transactions, so that there is a separate queue for each of the following: 1) Counter for savings bank services (SB); 2) One counter for accountable services (A); and 3) Counter for stamps and stationary services (SS).
1. Calculate a customer's expected waiting time in each of the three queues
2. Calculate the average number of customers in each of the three queues
3. Calculate a customer's total expected time in the system for each queue
4. Calculate the average time a customer spends in the post office, averaged across all customers.
